-Overview
---------
-
-The most important new features in this version of CrystFEL are:
-
-- Stability improvements to the scaling algorithm in partialator.
-
-- Addition of "custom dataset splitting" in partialator.
-
-- "retry" indexing.
-
-- Per-pixel saturation values
-
-These changes have sections below.  In addition, there were many bug fixes and
-smaller improvements.
-
-
-Stability improvements in partialator
--------------------------------------
-
-The scaling algorithm in partialator has been altered such that only the strong
-reflections contribute to the scaling factors at all.  This reduces the
-"drifting" of scale factors which happened before, and helps avoid the situation
-where a very large number of crystals get rejected with large B factors.
-Of course, all reflections contribute to the final merged data set as before.
-
-In CrystFEL 0.6.1, we needed to reduce the amount of noise going into the
-scaling algorithm to make it work.  This was done by including reflections only
-up to the apparent (conservative) resolution limit of each crystal made by
-indexamajig, and could be overridden by using the "--push-res" option of
-partialator.  The default --push-res value was zero, which meant to ignore any
-reflections higher than the limit.  With the stabilised algorithm, this is no
-longer necessary, and hence the default --push-res value has been changed to
-infinity, i.e. no cutoff at all.  You can restore the old behaviour with
---push-res=0.
-
-
-Custom dataset splitting in partialator
----------------------------------------
-
-When performing a time-resolved or isomorphous replacement experiment (plus some
-other types of experiment), it is preferable to ensure that the data for all
-time points has been processed identically.  Rather than processing each time
-point independently with separate runs of partialator, it is better to process
-them all together and do the splitting into time points just before the final
-output.  Consider, for example, the case of simple scaling (without a B
-factor): when merging independently, the resulting datasets would probably end
-up with different overall scaling factors.  When comparing the results, you
-would need to take this difference into account.  In practice, most programs
-can do that job easily, but what about if a B factor is included?  And what if
-partialities are included - how unique is the solution?
-
-Partialator's new "custom dataset splitting" option allows you to provide a
-text file containing a list of filenames, event numbers and dataset
-names, one event (detector frame) per line.  All crystals will be refined
-together, but they will be merged according to the dataset names you give.  The
-parameters (scaling factors, partialities etc) determined during the joint
-refinement will be applied.  For each dataset, a separate pair of split
-half-datasets will also be written, allowing you to calculate figures of merit
-such as Rsplit and CC1/2 for each one.
-
-
-"retry" indexing
-----------------
-
-If an indexing method fails to index a pattern (or if the solution doesn't get
-through the prediction refinement stage), this version of CrystFEL will delete
-the weakest few peaks and try again.  This can increase the indexing yield a lot
-(sometimes a factor of two!), but decreases the speed.  If you'd rather keep
-things fast, add "-noretry" to each of your indexing methods.
-
-
-Per-pixel saturation values
----------------------------
-
-When using dual-gain mode on the CSPAD (or any other detector which offers a
-similar feature), our current advice is to correct the pixel values in one of
-the regions by multiplying them by the relative gain factor.  This will give
-image data which looks good, but the saturation values will be different in the
-two regions.  To handle this, CrystFEL 0.6.2 allows you to prepare a map, in
-HDF5 format, giving the saturation value for each pixel individually.  The
-script "gaincal-to-saturation-map" can be used to create a suitable file from
-the gain map (e.g. as generated and used by Cheetah).  Specify the filename and
-HDF5 path of the saturation map using saturation_map and saturation_map_file
-in the geometry file - these work exactly like the bad pixel map.  Reflections
-containing any pixel above this value will be rejected, in addition to any
-reflections which get rejected by the usual saturation criteria (so remove any
-max_adu directives if you want the saturation map to be the only decider!).
